A powerful burst of high-energy light has swept through the solar system, scientists have revealed. This cosmic eruption was actually caused by a flare from a distant neutron star.
Trending
Scientists record these bursts of light relatively frequently - they can appear daily, on some occasions.

On April 15, 2020, a brief burst of high-energy light swept through the solar system, triggering instruments on several NASA and European spacecraft. Now, multiple international science teams conclude that the blast came from a supermagnetized stellar remnant known as a magnetar located in a neighboring galaxy.
This finding confirms long-held suspicions that some gamma-ray bursts (GRBs) - cosmic eruptions detected in the sky almost daily - are in fact powerful flares from magnetars relatively close to home.
